Best method for checking if IonCube Loader is installed

I'm using the following code:

<?p开发者_如何学Pythonhp
if(extension_loaded("IonCube Loader")) {     
  // Yes
}
else {
  // No
}
?>

I'm just concerned that this won't work across every server with IonCube enabled. It seems pretty standard, but I've never needed to check before. Is this the best way to check, or is there a better method I should be using?

If the extension is not installed this will return you false, so as far as I know it is the correct way to check if an extension is available to use.

Another option is to use get_loaded_extensions(). This returns you an array with available extension names. You could check if this arrays contains your desired extension.

Actually i use SSH for the most of the things, including file copy. When i need to check for ionCube loader the easier way for me it's just php -m.

Zend modules are listed on the bottom, due to the alphabetical order.

My output (last 2 lines): [Zend Modules] the ionCube PHP Loader.

For other options i used php -m | grep -v grep | grep MODULENAME. If it's loaded is listed, otherwise you will get empty. (except if you forgot the grep -v grep pipe).

Here the PHP code encrypted with latest encoder v9.0(PHP 5.6/7.0), if ionCube loader is working you should see text "working", if you see blank page check for php logs:
